RO sans DI

[ari5736]

The water coming out of RO is TDS 7. My DI is exhausted and more is on the way. Can I use straight RO for time being on a small polp coral reef tank?

That's kind of risky with acros that need low nutrients but as long as you're running a phosban reactor with media in it,it should be ok til you get your DI straight.
